To all whom it may concern.-

Be it known that We, WILLIAM W. TUOK,- residing at Richmond Hill, andAUGUST;

WASSMANN, .residing at Halletts Point, Astoria, Queens county, and Stateof New York, citizens of the United States, have invented certain newand useful Improvements in Ignite'rs for Hydrocarbon-Engines, of whichthe following is a specification sufficient to enable others skilled inthe art to which the invention appertains to make and 'use the agas-engine cylinder and combustion-chamber, showing diagrammatically andsymbolically the electrical connections. Fig. 2 is a horizontal sectionupon plane of line 2 2,

Fig. 1. i

0 represents the cylinder of any ordinary gas-engine, in whichreciprocates the usual piston I. I is a globular ignition-chamber, thelower portion of which consists of an extension 11' of the cylinder-headz' and the upper portion of a cap 7?, bolted to the lower section. It isobvious that the form and construction of the ignition-chamber I is ofsecondary importance, since our ignition-plate may be used in connectionwith various types of gas-engines.

As shown in the drawings, the ignitionplate A is flat and circular ingeneral outline, being formed with two extensions a a, which passthrough insulating-plugs b, inserted in the lower section c" of theignition-chamber. The outer ends of these extensions (1, a, areconnected electricallylwith the electrical circuit E, in which abattery6 or other source of electricity is interposed, so that when the circuitis closed a current of electricity will pass through the ignition-plateA sufficient to raise said plate to a temperature equal to the point ofignition of the hydrocarbon used,

jector B.

which is injected into the ignition-chamber I and against theignition-plate A by any suitable or well-known means, as through an in-(Shown symbolically in Fig. 2.)

' The current is maintained until a sufficient number of charges havebeen fired to thoroughly heat the parts, when the circuit may be broken,the succeeding explosions thereafter being relied upon to maintain therequisite ignitiontemperature.

Weprefer to form our ignition-plate A with a series of holes a for thepurpose, primarily, of increasing the superficial area exposed to theaction of the hydrocarbon spray or vapor, thereby facilitating andperfecting combustion. Incidental in this connection the openings alighten the structure.

What we claim as our invention, and desire to secure by Letters Patent,is

1. The combination with the ignition-chamber of a gas-engine, of anignition-plate disposed centrally within said chamber, with its outeredge substantially concentric with the walls of said chamber and havingintegral extensions passed through insulated openings in the oppositewalls of said chamber, and electrical connections with the outer ends ofsaid extensions, substantially as and for the purpose specified.

2. The combination with the ignition-chamber of a gas-engine of globularform in sections, the lower section forming an extension of thecylinder-head with flanges, and the upper portion being a cap withcoincident flanges, the lower portion being formed with openingsin itsopposite walls, insulatingplugs inserted in said openings, a flatsubstantially circular perforated ignition-plate disposed within saidchamber with its edge substantially concentric with the walls of thechamber and formed with divergent integral extensions held in and passedthrough said plugs, by which the plate is supportedlin position, andelectrical connections with the ends of said extensions, allsubstantially as and for the purpose specified.
